XBB.1.16 with NS3 V13L mutation (aka ORF3a V13L) has been proposed by @siamosolocani but has not been designated yet.

#H5N1 #LessonLearned - Domestic and Farm cats!

Common theme among H5N1 clade 2.3.4.4b infected Cats:
- Present multiple symptoms almost immediately
- Neurologic, Respiratory, rapid decline leading to death
(or compassionate euthanasia)
- Pick PB2 mammalian adaptations

1/n Image
French Cat (2022)

Phylogenetic analysis linked the infection closely to virus circulating in the neighboring duck farm, with minor genetic differences.

Key mutations: PB2 E627K & NS: E26G

Again, rapid selection of mammalian adaptation mutation

2/n
Polish Cats (2023)

First widespread H5N1 clade 2.3.4.4b infection across a wide geographic area within a country

Outbreak affected both indoor/outdoor cats

Cat food/ Stork investigated as a likely sources

Mammalian adaptations: PB2 E627K & K526R

It's getting difficult to separate GBW airport vs baseline screening

#30DayTrends GBW uploaded 275 sequences
out of which 69 airport seqs & 206 baseline surveillance seqs

Here is a detailed account of their surveillance efforts

#SARSCoV2 #VariantProportions - #USA |04/12/24

@CDCgov #Nowcast 2-Week estimates

JN.1* is still the dominant circulating group of lineages

Expected JN.1.11.1* sub-lineages (KP*) and others with #FLiRT mutations to feature in the dashboard



1/n covid.cdc.gov/covid-data-tra…

#FLiRT lineages are growing 👀

Nearly 20% of JN.1.13 (listed in CDC dashboard) is KS.1 (JN.1.13.1.1; not separated from the parent lineage yet)

and 55% of JN.1.16 is JN.1.16.1

Both KS.1 and JN.1.16.1 are #FLiRT lineages
